invention relates a self locking mailing circular, andf` particularly toone which has a doubled `flap for insertion in a slit` to .securely lockthecircular in closed 1n foldedconditionbya doubled Hap which Hapisfinsertedvin a slitin thelcir'cular and.

Mailing circularsare madein many and various styles including singleIsheets folded about to be` from one end towards the other and also withf side panels whichare folded over one an-` other and then thefwflrlole`folded into a com- .pactjpackage such as that shown in Figure l.

The blank chosen to illustrate the present invention issomewhatdiagrammatic in formv 4and it is to beunderstood that the linvention isnot limited to a circular made inv thestylev and arrangement as shownbut that the in-` i ,-pvention applies to anytype of mailing `Cir..v-cular.l *A v w ,t .tp Y

Thel illustrated form of the invention in-.

The slit 7 is formed in. any suitable part of the body A in such ositionthat when the circular is folded the a C will readily enter the slit.The portion may be provided with undercut corners 8 and 9 for lockingthe `flap C in the slit 7. However, these corners ma be square orslightly curved as desired.

he side of the folded circular opposite to that shown in Figure 1 isuseful for receivin the address and postage for transmittal o thecircular by mail.

The circular illustrated may be folded from the end ortion of the body Ainto what is shown in t e drawings as six plies or sections thusbringing the section containing the slit 7 in the position shown in thedrawin s. The iap C is then inserted in the slit 7 iy graspin the end 5of the portion 5 and pushing the old 4 into the slit 7. The ortions 5and 6 of the part B constitute a we ge so that whenthe same are insertedin the slot 7 a spreading or wedgin action takes place between the flapB an the portion 11 of the body A immediately below the slit 7. Thearrangement of the flap C is such that when thesame is inserted in theslit 7 a crim ing actlon takes lace between the iap B an the portion 11o the bod A at the slit 7 as is shown 1n Figure 2 o the drawings. Thisconstruction of the several parts securely locks the ia C in the slitwithout the requirement o further fasteners such as stickers, clips, andthe like. The depth of the' portions 5 and 6 of the flap B is such thatwhen the flap is inserted in the slit 7 it will extend a considerabledistance below said slit wlthin the rtion 11 of the circular body.

his aswely as the crim in action between e portion lldand the a securelylocks the ap in the circular. he free end of the asped as is indicatedin igure 4 for inserting the fold 4. in the slit 7 or for withdrawingthe flap from the ciring side edges of t e body A as the same appears inFigure 31and may be of any size or arrangement or number of folds.

' The gist of the invention resides in the p rovislonof a free portion Bfolded provide the folded edge 4 for insertion in a slit 1n the body ofthe circular and thus rovida tree end for inserting and with rawingortions folded along the lateral the `flap with the flap constituting awedging or spreading action to ether with a crimpingeifect between theap and slit. f

he connection between the free portion B and the body A of the circularis not folded so that when the flap C is bent over and inserted in theslit 7 there will be a spring action in the curve 12 which tends toforce the flap C downwardly into the slit 7 and thus aid in lholding theila closed.

The circular when folded is compact and` convenient for mailing and whenextended is opened for the usual purposes.

The invention has been describedherein more or less precisely, yet it isto be understood that changes may be made in the arrangement andproportion of parts and that equivalents may be substituted withoutdeparting from the spirit and scope of the invention.

The invention is claimed as follows:

1. A mailing circular including a body foldable into compact form, afree end portion inte al with said body, said body having a sllttherein, said end portion being folded transversely thereof intermediateits length, said folded free end constituting a flap insertable in saidslit when said body is folded.

2. A mailing circular including a body foldable into compact form, afree end ortion integral with said body, said body aving a slit therein,said end portion being transversely folded intermediate its length, saidfolded free end constituting a fla `insertable in said slit when saidbody is fol ed, and the free end of said iiap constituting prehensibleieans for inserting and withdrawing the 3. A mailing circular includinga body foldable into compact form, a free end portion integral with saidbody, said body havfing a slit'therein, said end portion bein foldedtransversely lntermediate its lengt said folded free end constitutin afla insertable in said slit when said bo y is olded, said flap beingcrimped when in said slit for locking the same in folded condition.

4. A mailing circular comprising a blank which may be vfolded intocompact form for mailing, said blank having a free end ortion, saidblank having a slit therein, said Free end portion being doubled on atransverse line and -`l',insertable in said slit when said blankisfolded for locking the same in folded condition. 5. A mailing circularcomprising a blank which may be folded into compact form for mailing,said blank havin a slit therein, said blank having also a ree endportion l which may be doubled transversely intermediate its length andinserted 'along the doubled edge in said slit when said blank is foldedfor locking the same in folded condition,

said folded end constituting a flap which is 1 retained in said slit byreason of the folded nature of the flap and the tendency of the foldedparts to spring apart.

6. A mailing circular comprising a blank which may be folded intocompact form for mailing, said blank having a free end portion, saidblank having a slit therein, said free end portion being doubled on atransverse line and constitutlng a flap insertable in said slit whensaid blank is folded for locking the circular in folded condition, theconnection between the blank and the free end portion being unscored forproviding a spring-like action foi` the retention of thelflap in saidslit. In testimony whereof I have hereunto subscribed my name atChicago, Cook County,

Illinois.
